The Fiat Doblò (with passenger's air bag ) is fitted with pretensioners on the front side seats to improve the protection provided by the seat belts.

These devices “feel”, that a violent collision is in progress via a sensor and pull back a few inches of webbing. In this way the pretensioner ensures that the belt is adhering perfectly to the body before the belt begins to hold back the wearer.

The seat belt locks to indicate that the device has intervened; the seat belt cannot be drawn back up even when guiding it manually.


The pretensioner will give maximum protection when the seat belt adheres snugly to the wearer’s chest and hips.

Some smoke may be produced when the pretensioners are fired. This smoke is harmless and does not indicate the principle of a fire.

The pretensioner does not require any maintenance or greasing. Anything that modifies its original conditions invalidates its efficiency. If due to unusual natural events (floods, seas storm, etc.) the device has been affected by water and mud, it must necessarily be replaced.

Operations involving banging, vibrations or heating (exceeding 100°C for a maximum of 6 hours) in the area around the pretensioner may trigger or damage the device.

Vibrations from rough road surfaces or accidental jolting caused by mounting pavements etc. do not have any effect on the pretensioner. If, however, you need any assistance, go to a Fiat Dealership.

This device reduces the load with is normally exerted by the seat belts on the passenger’s shoulder and chest in a collision. It increases protection by preventing the micro traumas which are inevitable in road accidents (also in vehicles with airbags). The device is built into the belt reel.
